DRIVING-GEAR.

Specification of Letters Patent.

PatentedQct. .5, 1915.

Application filed October 15, 1913. Serial No. 795,219.

1 0 all whom it amt concern:

Be it known that I, MAURICE E. BLOOD, a

citizen of the United States, residing at" Kalamazoo, Michigan, have invented certain new and useful Improvements in Driving-Gears, of which the followingis a specification. i

This invention relates to improvements in driving gears.

My improvementsrelate particularly to driving gears for motor vehicles adapted to be embodied in the hubs of the driving or traction Wheels, and especially, Wheels for light motor vehicles of the type commonly designated as cycle cars.

The main objects of this invention are: First, to provide an improved driving gear for motor vehicles. Second, to provide an improved driving gear for motor vehicles adapted to be embodied in the hub of a Wheel such as is commonly employed on motor vehicles of the cycle car type. Third, to provide an improved driving gear, embodying these advantages, Which is simple and compact in structure, practically noiseless, and one which is very durable in use.

Further objects, and objects relating to structural details, Will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims. I a a A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is an outsideelevation of a Wire wheel embodying the features my mvention. Fig. II is a detail horizontal section on a line corresponding to line 22 of Fig.

I, of a motor vehicle structure embodying the features oi my invention. Parts being shown in full line for convenience andclearness in illustration. Fig. III is vertical section through the mechanism on a line corresponding to line 33 of Fig. II." Fig.

IV is a detail section on a line correspond- I ing to line 4t4 of III. Fig. is a perspective vievv of the resilient split ring member 19. Fig. VI is a sectional view provements. ClI'lVlIlg' or traction Wheels, as the other is a corresponding to that of Fig. III, of a modified struc ture, the intermediate aniiiilar member 1( present in Fig. V being omitted. in the dravungs s milar reference char 'acters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the endsof the section lines.

In the accompanying drawing I have illustrated only'such parts of amotor ve hicle as are necessary to illustrate my im I have shown only one of the duplicate thereof. a

The transmission shaft 2 is connected to the driving shaft 1 by means of the beveled gears 3 and 4:, gear 4 being secured to the driving shaft 1. i

The Wheel shown is of the Wire type and provided with a flange 6 having a rim? thereon forming a hub chambered at its outer end.

.9 coacts. V j

The means for operating the brake memher are not illustrated as they form no part of my present invention, 1

A driving member 10 is secured to the driving shaft by means of the keys 11 and a nut 12. The driving member 10 is pro vided with a peripheral groove 13, While the rim 7 is provided with an internal peripheral groove 14..

The driving member-'10 isprovided with a driving lug 15 disposed in its groove, While the hub is provided With a driving log 16 disposed in its groove. I j a A ring or annular intermediate member 17 is arranged. Within the hub and provided with an external driving lug 18 disposed in the groove l t to coact with the driving lug The hub 5 is provided with a 1'1111 flange 8 With which the brake member 16 oi the hub, it being otherwise free for independent rotative movement, thatis, the hub and member 17 may rotate independently for substantially one complete revolu} 'tion.

The member 19 is provided with out- Wardly projecting lugs 21 at each end Which the member 17 to coact with the internal driving lug thereof.

Forconvenience, the lugs 18 and 2-3 are disposed oppositely'and secured by the rivet 24, common to both.

The shoe 22 is provided with a slot 25 with which one of thelugs 21oz the member 1.9 is engaged, and with a slot 26 adapted to receive the other lug 21.

The sloti26 is of such length as to form a lost motion connection between the end of the resilient member having the driving lug 2O thereon and the shoe. This resilient member 19, owing to its resilient quality, serves as a shockabsorber and also serves to pre ent rattling or noise.

In the modified structure shown in Fig. VI the intermediate ,annular .member" 17 =is omitted, and the shoe 22 coacts directly with I thedriving lug-16 on the driven member 5.

Theparts are retained in their assembled relation by meansof the retaining plate 27 seated against a shoulder 28 within the hub andretained therein by the hub cap 29.

' Both driving wheels being equipped with the mechanism described they are connected to the driving shaft so thatin turning or in other cases where one wheel travels faster than the. other the driving lug 18 of the gear 7 17 will move from the driving lugs 16 until it engages the opposite side thereof should the difference in speed be suflicient to cause this and if the difference be great enough the shoe will swing from the driving lug until it engages the opposite side thereof. This is sufficient to accommodate any ordinary variations. Vhen the vehicle returns to its straightaway the parts return to their driving. f r

In the structure illustrated the partsare all simple andeconomical to produce and very easily assembled.

I have, as stated, especially designed improved. gearing for light motor vehicles of the cycle car type. It is, however, adapted for use in various relations. I have'not; attempted to illustrate or describe various modifications or adaptations possible as I ters Patent is:
